Looking for information about AS3 sound classes in "audio" wrong places?

Question

I'm looking for in depth information about ActionScript 3.0 sound classes. No matter where I search I continually encounter the same sort of kindergarten level descriptions, which never teach more than what we can readily glean from Adobe's documentation. Someone must know where there a discussion that really gets to the heart of the matter.
I've read Adobe's LiveDocs on the Sound, SoundChannel, SoundMixer, SoundTransform classes. Indeed, they provided me enough guidance to create my own streaming MP3 player, with volume, pan, my own custom mono mix, http request, a preloading animation, and peak meters ...
Here's an example (in the last statement of the following code) where I understand the end effect, but I fail to comprehend what happens at the compiler level:
var currentSoundSource:Sound = new Sound();
currentSoundSource.load(new URLRequest("http://www.mySite.com/myRecording.mp3"));
var audioChannel_01:SoundChannel = new SoundChannel();
audioChannel_01 = currentSoundSource.play();
Unfortunately the class definitions in LiveDocs are quite terse, and they're seemingly incomplete with respect to:
     •     advice on best practices
     •     a thorough coverage of class to class interactivity
     •     a description of exactly how audio streams/plays into channels
... and in certain cases it appears that Adobe's descriptions are not fully accurate.*
Regarding best practices, at first blush I'm sure everyone ponders over the fact that SoundChannel and SoundMixer have a stop method while the Sound class does not.
One assumes that this surprising design must bear some advantages. If so,  what are they? Where are the analog sound mixer analogies? What would be the disadvantage of a sound class with a stop method ...  particularly when they have their own play method?
Where are the discussion of these concepts? (Even if Adobe hired the wrong guy to write its sound classes, there should be some follow through that thoroughly explains the existing situation.)
Phrankie
* Here's an instance where the docs appear to be partially in error. (Is "and play" mistakenly included in the following?)
"The Sound class lets you lets you create a new Sound object [and] load and play an external MP3 file into that object."
... uh, mmmmmm ... we play an MP3 into a sound class object?
Wouldn't it be more accurate to say the following:
A soundChannel can receive the audio data from a sound class object. We can play a sound object into an SoundChannel and manipulate it by altering the SoundChannel's soundTransform property, and we can stop it with the SoundChannel's stop method.
